I’m in.
I’ll make a treeclimbing creature that escaped when the elves where being converted to orcs, went east, and evolved there to live in the trees.
They write thier historie on the trees, and a individuals on thier skull. I’m going to make one thats busy writing something into a tree.
They despise the orcs, although their ancestors almost became them, and sometimes have a orc skull with the word “shame” ingraved on it.
they live in forests with a wide selection of trees, and the histories are written in the smooth skinned ones.
Thier partial conversion to orcs leaves them with less love for the woods, and will destroy trees if they see a significant advantage in doing so.
they will not blindly destroy anything.
I’m still trying to think of a name and im still trying to make a concept sketch that i think you may undrstand
